The SpeedyBee VTX-DVR is an all-in-one solution for those wanting high-quality onboard DVR recording and VTx in one board. The VTx supports Betaflight, CMS, and IRC Tramp.
The factory default setting is in lock mode with red LED blinking and only 25mW is available. You can switch to unlock mode by long pressing the button for 10 seconds with the red LED constantly on.
Note: Before you get VTX unlocked, it is highly recommended to know about the rules and regulations in your country about the frequency to avoid a fine or confiscation of your device.
